Used as a coupling reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of pharmaceuticals, agrochemicals, and organic materials. The tert-butyl group enhances stability and influences electronic properties, improving reaction selectivity. Its boron-based structure allows for mild reaction conditions and compatibility with various functional groups, making it valuable in late-stage functionalization during drug development. Often chosen for constructing biaryl systems found in bioactive molecules.
